this chart on the blog post gives me the impression that read replicas will pretty much always be under a second behind the primary.
is this impression accurate?

A

ajgeiss0702•4/10/25, 6:36 PM

also, when the sessions api was announced last year, IIRC it was stated that if you used the old (non-session) D1 api, the behaviour would be the same as it is without replication (always go to the primary) but now this graphic suggests otherwise. did this change?

yea, I don't think the blog does a great job of explaining it, but you can see in the code itself, if just using the methods on the binding itself, it only goes primary

I get that too, but last I saw they were recommending people retry the request when reciving that error

Mozzy•4/10/25, 7:39 PM

occasionally, but, started a few hours ago. Could be read replication perhaps, but the error isn't helpful

Any particular region?

ajgeiss0702•4/10/25, 7:44 PM

that might have been around when I enabled replication for that db, but i didnt record exactly when I enabled it so im not sure.
but the workers arent using the session api at all yet

MMilan Any particular region?

A

ajgeiss0702•4/10/25, 7:45 PM

the database is located in WNAM, let me check the colo of the requests with errors

A

ajgeiss0702•4/10/25, 7:48 PM

there doesnt appear to be a common colo. some in europe, some in asia, and a few more errors from YYZ and Chicago (which are the colos that my site gets the most requests from anyway)

Is it possible to create new databases dynamically yet? Or are we still stuck with being unable to on-the-fly create and interact with them?
